SPECIFICATION forming part of Letters Patent No. 649,403, dated May 8, 1900.

Application led December 30,1899. Serial No. 742,049. (No model.)

To @ZZ whom, it may concern: l, taken on the line a' and looking toward Be it known that I, ALVAH W. CLEMENT, the right.

a citizen of the United States, and a resident The loom-frame A, lay A3, breast-beam A40,

The swing imparted to the paWl-carrier stores up energy in the spring, and the latter will When free to act rotate the feeder by or through the pawl-carrier, pawl e2, and ratchet a9, the arm h having been raised by the retu rn vstroke of the transferrer.

The casing e2@ is provided with a stop @22, which engages the paWl-carrier and positively limits the spring-impelled motion of the pawlcarrier, relieving the arm h from shock, and preferably the paWl-carrier is stiffened and strengthened by a web 18, Fig. l, extended along one edge to take up and distribute the blow when the stop @22 is engaged.

The actuating means for the feeder is controlled by or through the operationoof the transferrer in the construction shown, and the upper portion of the lay is relieved from the duty of setting the feeder-actuating spring.

The durability, strength, and direct action of the apparatus are enhanced by the construction set forth, one practical embodiment of the invention being shown and described Without attempting to show various modifications thereof which might be made Without departing from the spirit and scope of the invention.

It will be manifest that while the stop e22 limits the movement of the pawl-carrier in one direction, thus preventing shock to the arm h',- which would tend to loosen it on the shaft f, the limit of the feeding movement is determined by the strength of the spring s and the momentum of the parts moved-viz., the filling-feeder, its load, rbc.

The mechanism is so arranged that if there is a gap-t'. e., several filling-carriers missing from the feeder-the spring s will give sufficient impetus to the parts actuated thereby to carry the feeder around to the proper point with a filling-carrier in position to be transferred.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A filling-feeder to hold a series of llingcarriers, means to intermittingly actuate the feeder to bring the filling-carriers singly intd operative position, a transferrer, and con nections between the actuating means and the transferrer, to set the former by the operation of the latter.

2. A rotatable filling-feeder to hold a series of filling-carriers, an attached ratchet, a cooperating pawl, a pawl-carrier, a feeder-actuating spring, set by retraction of the pawl carrier, a transferrer, and means controlled by operation of the transferrer to retract the paWl-carrier and thereby setthe spring, the latter acting through the pawl and ratchet to rotate the feeder intermittingly and bring the filling-carriers singly into the path of the transferrer.

3. A rotatable filling-feeder to hold a series of filling-carriers, an attached ratchet, a cooperating pawl, a pawl-carrier, a feeder-actuating spring, set by retraction of the pawlcarrier, a transferrer, means controlled by the operation of the transferrer to retract the paWl-carrier and thereby set the spring, and a shield to determine the point of engagement of the pawl and ratchet upon spring-actuated movement of the pawl-carrier.

4. A rotatable filling-feeder to hold a series of filling-carriers, an attached ratchet, a cooperating pawl, a pawl-carrier fulcrumed coaxially with the feeder and having an at tached cam, a feeder-actuating spring attached at one end to said pawl-carrier and set by retraction thereof, a rocking transferrer, and an arm movable therewith io engage the cam and retract the pawl-carrier when the transferrer is operated, the feeder-actuating spring when set acting through the pawl and ratchet to rotate the feeder to bring the filling-carriers singly into the path of the transferrer.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
